There are over 80 meds that are commonly used for ADHD, because they just plain and simple don't work for everyone, and even when they do work; they work *differently* with everyone. Neurochemistry is a touchy thing. We've all got our own unique combos and patterns. Adderal, for example, has the nickname 'Adderage', because aproximately half the ADHD people who take it start having *major* temper issues. Why is it still on the market? Because the OTHER half it doesn't affect their mood at all!
It's VERY common/ expected that when you start meds 3 things will happen:
1) You'll start out at the lowest dose possible (to double check for allergies, negative reactions, side effects at the lowest possible level), work your way up to BEYOND what you want to be taking, and then work your way down to the level that 'feels right'. There's a "sweet spot" with meds where you nixing the max of the things you don't like, while leaving the max of the things you do. It takes about 3 months, usually, to do the work up and work down.
2) You're going to be trying 2-5 meds your first year unless you get LUCKY. There's no 'test' to see what med will be best for you, nor what side effects you're going to have from them. Side effects are often GOOD things (like being able to sleep when you want to, or not having to fight to control your temper), but all meds have them. They all FEEL different.
((By max dose... you're saying 160mgs of Straterra??? In a TEN yo? I've been on that dose. Standard dosing is 80mg))
3) You'll STILL NEED TO be learning coping mechanisms. Meds aren't a magic wand. The right ones are an 'easy button' which make things a gazillion times easier... but you still have to WORK.
It's reeeeeeally common for 1 or more meds to 'have no effect', it's also reeeeeeally common for 1 or more meds to have BAD effect (aka make things harder). Those are the WRONG meds, or at the WRONG dosing levels (and higher isn't better. Neuro drugs aren't like taking tylenol with a headache. If it isn't working taking more works with pain killers, but sometimes when a med 'isn't working' you take LESS with neuro drugs).
Now... personally... I'm ADHD-c, and I don't take meds. I DO take stimulants (caffeine and nicotine)... i'm not chemically free by ANY means, and my son is med free (but he has an inhaler for asthma-type that works wonders in conjunction with caffeine). IF he were in most awayschools (we homeschool) he would soooooo need to be on meds. Otherwise it would be a waste of time for himself and his teachers. ((Note the "most")).
I am NEITHER PRO NOR ANTI meds. Meds are tools. They can be useful, or get in the way, depending on the situation.
What my mum did (and what *I* would do if I decided to send my son to awayschool) is this: We'd try out different meds over school breaks. That way she (I) could SEE what the effects were, monitor the dose to effect, and we could make a joint decision together on whether or not to try them at school.
This is NOT a "teacher-choice", this is a PERSONAL AND FAMILY choice on whether or not to medicate.
For MYSELF we found that the best option was gifted/AP classes (and that's a standard ADHD trick, we get bored in normal classes and flunk them out of sheer flatline not paying attention) and a boatload of caffeine. Many many meds "worked" (as in I could become a 'model student'), BUT I LOST too many of the aspects I like about myself (not a zombie by any means, but ADHD has a lot of POSITIVE aspects as well). As an adult very very LOW level meds have been wonderful ((I'm off the charts scale wise, whenever I decide to try a new med my team always plans on going to twice the normal levels to the max dose, and working down)), and ONE med has been perfect!!!!! (at double the normal level). But it's a logistical nightmare to acquire because it's HIGHLY regulated (hello, coca). Single pharmacy ONLY, traveling the dogs go after me at the airport (and I travel a lot), travel time is limited to how many pills I can be prescribed (because of that single pharmacy rule). UNLESS I MOVE TO THE ANDES (where people chew coca leaves, and there's coca tea, and it's just not strictly regulated like it is here) I won't be on my personal 'easy button'. I'll drink coke/pepsi/mtnDew and smoke cigarettes/chew gum. It's enough to take the edge off.
In the meantime.... check out www.additudemag.com for coping mechanisms AND med info. A person doesn't HAVE to be on meds for their adhd... it just takes longer / is harder to learn things that are easy for neurotypical kids.
